Abstract

Introduction: Because their ability to capture CO2, photosynthetical microorganisms have some advantages to CO2 mitigation from high CO2 streams such as FLUE GASes and they can use CO2 as carbon source. Recently, experts have made efforts to exploit microorganisms intended for recovering CO2 from power plants.Materials and methods: To achieve this purpose, we studied the growth response of the cyanobacterium SPIRULINA PLATENSIS PCC9108 under different concentrations of carbon dioxide (ranging from 0.036% to 10%) and FLUE GAS in a bench-scale system. Preparation of different concentrations of CO2 and injection into Erlenmeyer flasks was performed by a system including air compressor, CO2 capsule, pressure gauge and flow meter.Results: The main goal of studying this paper is a survey of organism's potential to grow by generated CO2 from FLUE GAS of power plant. It already had the potential and highest BIOMASS PRODUCTION recorded at 8% CO2 (v/v). Also we proved that S.platensis PCC9108 can be grown under FLUE GAS, although BIOMASS PRODUCTION decreased fairly. TOTAL LIPID CONTENT of algae interestingly enhanced with elevated CO2 levels from ambient air to 4% and 6% which ranged from 14.5 to 15.8 and 16 dry weight (wt.) % respectively. In contrast, TOTAL PROTEIN CONTENT illustrated no difference between all treatment and its value was about 46 wt.%.Discussion and conclusion: The results of present study suggested that understudied S.platensis PCC9108 is appropriate for mitigating CO2 because of its carbon fixation ability. Also due to its high protein content, this cyanobacterium is a good candidate to produce SCP (single cell protein).
